Where can you get ammunition for a 38 Colt Police Positive concealed weapons class?
Your weapon would take the 38 special.
Be careful with the older Colt Double Action Revolvers. If the
barrel indicates 38 "Special" - only then would it take that
cartridge. Typically if the barrel states 38 New Police the
revolver with take the 38 S&W ammunition, either short or long
depending on the length of the cylinder (Colt could not bring
themselves to roll stamp S&W on their revolvers. When the
barrel shows just "38" this would indicate the 38 Colt Round,
either short or long - again depending on the length of the
cylinder.
